ESCOVA DE BORDA PARA TIRA ELETROGALVANIZADA

摘要

Apparatus is disclosed for brushing the edges of electroplated metal strip to remove excess plating metal therefrom. In a first embodiment for brushing the narrow face edges of the strip, a cup brush is mounted on a carriage having a motor thereon for rotatably driving the brush. The carriage is slidably movable in a transverse direction of the strip. A device urges the carriage inwardly toward the strip so that the brush is maintained in constant contact with uniform pressure against the strip edge. In a second embodiment for brushing the broad surfaces of the strip adjacent to the strip edge, a disc brush is mounted on a carriage having a motor thereon for rotatably driving the brush. Again, the carriage is slidably movable in a transverse direction of the strip. A device urges the carriage inwardly toward the strip so that the brush is maintained in constant contact with a uniform portion of the width of the strip near the edge thereof. A second device is provided for maintaining the pressure exerted by the brush against the strip substantially constant. In a preferrred form, a device is provided for removal and collection of plated metal particles brushed from the strip.
